The Blue Marble is a conversational Web3 interview show whose guests come to blockchain from very different starting points. One comes from beer and hospitality. In 'Blockchain and Beer - with Pete Kais (aka: Kasey)', the guest describes a directory for finding a local tap room and a digital magazine updated four times a year. He also covers the wallets, exchanges and point-of-sale systems that come with a beer token. Jessica Yarmey started Kickhouse as a gym during lockdown, and the talk with her turns to what might move people who are comfortable staying in Web2. Alejo Mendoza, founder of SKYHITZ, has built a place to upload, buy and sell music NFTs on the Stellar network. He argues that young companies stand a better chance when they build on very solid foundations. A second thread is environmental. Erin Grover works on using blockchain to bring transparency to carbon credit markets, and she has done field research on emerging DeFi markets in Kenya, Uganda and India. Steph L Dickson, founder of Green is the New Black, points to House Africa, which is building a property record system on the blockchain for home buyers and financial companies. Sam Goyal, founder of Singapore-based Solar Horizons, talks solar leasing from a village in Goa where the Covid-19 lockdown has left him stranded. The interviewer is Matt, and he does more than hold the microphone. He brings his own experience into the conversation, recalling an 18-month project in Malaysia before asking Erin Grover how nonprofit models compare with social enterprises. He is frank about NFTs, too. He calls the boom a bubble that has burst and points out that without the blockchain piece, an NFT is just a JPEG. He also presses on adoption, asking Alejo Mendoza what leaps are needed to speed it up and whether technology is even the main obstacle. The register is warm and easy. He already knows some of his guests, and the recordings stretch across time zones, his morning set against a guest's evening. Conversations start with small talk, such as Melbourne's four seasons in a day or a sarong in Goa, before settling into business. The Sam Goyal episode opens with a warning that the connection is rough at first but improves. Several episodes close with a sign-off for the Task Podcast and an invitation to get in touch with Matt or the team. It suits a listener who wants blockchain explained through the businesses using it, in plain business terms.
